The aeromedical assessment of human systolic and diastolic blood-pressure transients without direct arterial puncture by M. T Lategola( Book )

2 editions published in 1966 in English and held by 18 WorldCat member libraries worldwide

A system for virtually continuous measurement of both systolic and diatolic blood pressures without recourse to direct arterial puncture has been effected by the modification of already existing standard equipment. This system entails the measurement of systolic blood pressure with a digital pressure cuff on one arm simultaneously with the measurement of diastolic blood pressure from a bracial cuff mounted on the other arm. The systolic-pressure device was used virtually unmodified. The diastolic-pressure device was originally designed to measure both systolic and diastolic pressures automatically. The modification consisted mainly in the elimination of the systolic portion of the automatic cycle. The combined system is capable of routinely obtaining measurement frequencies in the order of 20 per minute for protracted time periods. The system functions well under all resting-subject conditions and under some 'body-movement' conditions. This system is currently in routine use in all our aeromedically oriented research involving the assessment of cardiopulmonary function
Manipulation of arousal and its effects on human vestibular nystagmus induced by caloric irrigation and angular accelerations by William Edward Collins( Book )

1 edition published in 1962 in English and held by 17 WorldCat member libraries worldwide

"Alterations in the nystagmic reaction of human subjects exposed to vestibular stimulation have been frequently noted in studies of drug effects, "habituation", and general features of the labyrinthine response. Wendt has maintained that, when visual stimuli are excluded, the primary source of intra-subject variability is the orientation of the subject. Specifically, Wendt has held that a brisk vestibular nystagmus is obtained so long as the subject remains "environment-directed" and does not lapse into a "reverie" attitude. The present report represents a compilation of the results of several experiments in which methods of controlling the psychological attitude of the subject were evaluated. Control features were then introduced in the examination of some basic theoretical and applied aspects of the vestibular response."--Introduction
Age and sex factors in the control of automobiles by Stanley M Soliday( Book )

1 edition published in 1972 in English and held by 15 WorldCat member libraries worldwide

"Forty volunteer subjects drove a specially instrumented car over an interstate highway course and over a heavily traveled urban course. Ten subjects were men over 30 years of age, ten were women over 30, ten were men under 30, and ten were women under 30. Several differences were found between vehicle control patterns of the men and women. Several smaller differences appeared between age groups. Finally, a comparison of interstate data wirh that of a previous study (Soliday and Allen, 1972) revealed consistency between groups, apart from a significant difference with respect to lane changes. As expected, the type of roadway course had a profound effect on the control patterns of all subjects."--Abstract
The relationship between numbers of leaflets disseminated and communication achieved by Otto N Larsen( Book )

1 edition published in 1954 in English and held by 13 WorldCat member libraries worldwide

This Research Digest is one report on Project “Revere”, AF 33(038-27522), a contract with the University of Washington, Washington Public Opinion Laboratory. This project is concerned with the dissemination of messages by means of air-borne leaflets. Research under the project has been conducted within the United States. The findings will be further tested by the Air Force overseas at a future date. How many leaflets should be dropped on a target population to achieve maximum efficiency in the diffusion of a message? Test 1 of Project Revere, based on extensive pretesting, was designed to provide some answers to this question. All the conclusions derived must, of course, be also considered in the context of specified target characteristics, general cultural conditions, specific message content, timing of the test, and the research procedures outlined below
An investigation of the accuracy of ortho-rater perimeter measurements by John A Allen( Book )

1 edition published in 1972 in English and held by 11 WorldCat member libraries worldwide

"This study was designed to assess the precision of the Bausch and Lomb Ortho-Rater perimeter in determining the lateral visual fields of individuals. Twenty-two college students with uncorrected vision were examined on both an Ortho-Rater perimeter and a more sensitive clinical perimeter. An examination of lateral visual field (LVF) values and total visual field (TVF) measurements indicated that 1) LVF values and TVF values may be generally lower (narrower) on the Ortho-Rater than those obtained on a device such as might be found in a clinical setting and 2) Ortho-Rater LVF measurements for right and left eyes may not detect actual (i.e., existing) LVF differences between eyes."--Abstract

Effects of combat simulation on the work-related motivation/satisfaction of participants by Robert H Sulzen( Book )

2 editions published in 1979 in English and held by 10 WorldCat member libraries worldwide

"To improve both the combat readiness of Army units and the psychological rewards derived from training, the Army Research Institute has developed a group of techniques for simulating battlefield conditions. These techniques are known collectively as Engagement Simulation (ES). The squad and platoon level application of ES is referred to a REALTRAIN. REALTRAIN can be distinguished from more conventional training along a number of dimensions, including the degree of operating constraints in the exercises, type of casualty assessment, nature of evaluative feedback, and sequence of training procedures. A paper-and-pencil instrument was constructed that measured six different dimensions of job-related motivation and satisfaction. Results indicated that along four of the motivation/satisfaction dimensions (Attitude Toward the Exercises, Military Work Role, Unit Cohesiveness, and Leader Improvement), responses were more positive following participation in REALTRAIN than before participation. In the remaining two dimensions, there was no change in the "before" and "after" measures of motivation/satisfaction. However, for the conventional exercises, there was no change in the before and after responses of participants along five of the dimensions. Along the remaining one, there was a decline in the satisfaction level in the conventional training."--Abstract
Anthropometric survey of the armed forces of the Republic of Vietnam by Robert M White( Book )

1 edition published in 1964 in English and held by 10 WorldCat member libraries worldwide

"An anthropometric survey of military personnel of the Republic of Vietnam was conducted between 28 May and 1 July 1963. Body measurements were obtained on a total series of 2,129 men consisting of 1,225 of the Army, 299 of the Navy, 301 of the Marine Corps, and 304 of the Air Force. Fifty-one measurements were made on each individual. The anthropometric data were analyzed and are presented in this report in the form of statistical values. It was found that the 50th percentile value for the stature of Vietnamese military personnel is equivalent to the 2nd percentile value for United States soldiers, while the 50th percentile value for the weight of Vietnamese is less than the 1st percentile value for United States soldiers. The average Vietnamese is about 5 inches shorter in stature and 43 pounds lighter in weight than the average United States soldier. The results of the survey may be utilized in the engineering design and sizing of clothing and equipment intended for use by the Armed Forces of the Republic of Vietnam."--Summary
Contributions of psychology to the study of pattern vision by Harold W Hake( Book )

1 edition published in 1957 in English and held by 10 WorldCat member libraries worldwide

"A survey is provided of major research topics in psychology having relevance to patterned vision--including the study of threshold measurements, visual distortion, form discrimination, constancy in form perception, memory for form, and training problems. An analysis of the perceptual task suggests that true fidelity in visual perception is not possible, but that the visual system does operate to produce to provide coherent reconstructions of visual stimulation."--Abstract
Errors in driver risk-taking by Paul M Hurst( Book )

1 edition published in 1964 in English and held by 9 WorldCat member libraries worldwide

"A viewpoint is presented concerning "accident" causes: essentially, that they are usually accidents, and not the results of willful negligence or other motivated behavior. Accidents result from confusion. A means is presented for measuring average degrees of driver confusion, and comparing these averages across different highway and traffic conditions. Suggested cross-validational procedures are discussed. The argument is set forth that "confusion", as operationally defined by the suggested procedure, will furnish a valuable intermediate criterion to investigators in the accident-prevention field."--Abstract
Psychological aspects of physical disability by James F Garrett( Book )

1 edition published in 1953 in English and held by 9 WorldCat member libraries worldwide

"As workers in the field of rehabilitation we are realizing more and more that we do not "rehabilitate" people. Rather we must be able to reach the heart and mind of the individual with whom we are dealing, so he will want to avail himself of the services our program can provide for him. His drive to accomplish his own rehabilitation must come from within himself and we must be sensitive too in the factors that can help or hinder establishing this indispensable primary base for rehabilitation. Increasingly we are learning that human motivation is influenced by many things. Especially important are the psychological and social factors of an individual's life. These factors are important to consider early in our planning for the whole program of rehabilitation for the individual and in the evaluation of each step of its development. This bulletin was written primarily for vocational rehabilitation counselors. It is expected that it will assist them in planning better rehabilitation programs. The need for awareness of the psychological adjustment mechanisms of the physically disabled is not confined to the counselor, however, and it is hoped that physicians, social workers, psychologists, and placement specialists may profit from the contents of this publication. The cooperation and coordination of the various specialties is the most important element today in providing rehabilitation services for the disabled whereby they may take their rightful place as contributing members of society. The interest and cooperation of the authors and the organizations many of them represent is a practical demonstration of the vital nature of the material presented herein. We are aware of the fact that successful rehabilitation programs depend on integrated community activity and in a sense this bulletin epitomizes that approach."--Foreword
Information processing in neurones and small nets by Anatol Rapoport( Book )

1 edition published in 1960 in English and held by 9 WorldCat member libraries worldwide

"The neurophysiological literature has been surveyed to determine the current state of knowledge on the characteristics of neurons as elements in information-handling systems. An extensive bibliography of over 450 reports bearing on this subject has been appended and abstracts of slightly over 100 papers which were felt to be most relevant to this subject have been prepared for this report. These abstracts together with comments by the present investigators have been compiled into the present report. The scheme of presentation and the general findings are covered in the author's preface. Detailed conclusions are found in the individual abstracts."--Abstract
Comfort evaluation of the C-97A/KC-97E pilot seat (Weber) : one of a series of studies pertaining to the design evaluation of pilot and crew station equipment by Robert F Slechta( Book )

1 edition published in 1959 in English and held by 8 WorldCat member libraries worldwide

"This study was undertaken in order to evaluate certain design characteristics of the C-97A/KC-97E Pilot Seat (Weber) in terms of their adequacy for the maintenance of human comfort The method of evaluation consisted primarily of a battery of subjective and behavioral laboratory tests administered by means of hourly questionnaires presented to sixteen subjects during a voluntary sitting period of seven hours' maximum duration. While the permitted maximum duration of sitting time was 420 minutes, the average voluntary time spent in the seat was 365.6 minutes. On a comfort scale ranging from intolerable discomfort (-10) to ideal comfort (+10), the average of the ratings assigned was +3.57. Hourly scale evaluations of the comfort of the seat revealed that, although the comfort provided decreased with time, at no point during the first five hours did the average rating fell into the discomfort zone. Hourly evaluation of discomfort in specific body regions indicated that for all body regions the average time of onset of discomfort was 198.0 minutes, and that the most discomfort was experienced in the buttocks, back, and neck, in that order. Evaluation of individual seat parts revealed certain inadequacies in the seat and back cushions, armrests, headrest, and manipulative aspects of the adjustment controls. On the basis of test data and specific comments made by the subjects, recommendations for seat design improvement are made."--Abstract
Protection and functioning of the hands in cold climates by United States( Book )

1 edition published in 1957 in English and held by 8 WorldCat member libraries worldwide

"Man's uniqueness is primarily a result of the exceptional development of his brain-hand "system". The capacity of man's brain for integrating imagination and judgment with the dexterity of his hands has permitted him to develop devices which possess enormous power and velocity. The limits of man's creativeness have not been reached nor, indeed, have they been anticipated; yet an interesting paradox has resulted. The same brain-hand system responsible for man's creations has been found to be the limiting factor enabling man to operate and govern his creations. During World War II the considerations of man's role in controlling his inventions began to emerge as a specific discipline which has come to be known as Human Engineering. Man, in this context, is considered as a component of man-machine-environment systems. Human engineering encompasses the physical sciences, engineering, meteorology, management policy, industry, and the various aspects of the biological sciences. Inasmuch as the part played by man is, in many cases, the limiting factor in carrying out necessary operations of systems, physiologists have become aware of problems new in scope and emphasis. While physiologists know a great deal about certain functions of man, great gaps in our knowledge of many aspects of biological function become evident when man is considered as part of a man-machine system. The participants of this conference have focused their attention on a single element of this complex man-machine system and the environment in which it operates: The Hand. The hand itself is a complex machine. Its mechanical function depends upon a number of variables. The understanding of hand function itself calls for great resourcefulness of physiologists, psychologists, engineers, physical scientists and those who decide what useful manipulations the hand must perform. Indeed, an understanding of hand function can only occur in terms of the over-all system of the man with his hands, the devices he operates and the environment in which he operates."--Foreword

The effects of shock and vibration on man : a report by David E Goldman( Book )

1 edition published in 1960 in English and held by 7 WorldCat member libraries worldwide

"This review deals with three problems: 1) the determination of the structure and properties of the human body considered as a mechanical as well as a biological system, 2) the effects of shock and vibration forces on this system, and 3) the protection required by the system under various exposure conditions and the means by which this protection is to be achieved. Man, as a mechanical system, is extremely complex and his mechanical properties are quite labile. He is also a human being and in this capacity refuses to permit destructive testing but will nevertheless expose himself carelessly to mechanical damage which may arise from situations of his own making and will then demand a degree of protection against this damage which shall be almost impossibly effective, unhampering, and cheap. Because of such conflicting attitudes there is very little reliable information on the magnitude of the forces required to produce mechanical damage to people. It is therefore necessary to use experimental animals for most studies on mechanical injury. However, the data so obtained must be subjected to careful scrutiny to determine the degree of their applicability to humans, who differ from animals not only in size but in anatomical and physiological structure as well. It is only occasionally possible to obtain useful information from situations involving accidental injuries to man, since while the damage can often be assessed, the forces producing the damage cannot. It is also very difficult to obtain reliable data on the effects of mechanical forces on the performance of various tasks and on subjective responses to these forces largely because of the wide variation in the human being in both physical and behavioral respects. Measurement of some of the mechanical properties of man is, however, often practicable since only small forces are needed for such work. The difficulty here is in the variability and lability of the system and in the inaccessibility of certain structures."--Introduction
Human engineering aspects of radar air traffic control : IV. A comparison of sector and in-line control procedures by Lowell M Schipper( Book )

1 edition published in 1956 in English and held by 7 WorldCat member libraries worldwide

"The present experiment is the fourth in a series of studies using the OSU Air Traffic Control Simulator. Experiments I, II, and III investigated the effects on system performance of different TRAFFIC and DISPLAY variables. This experiment was principally concerned with the evaluation of two types of two-man control procedures, an ORGANIZATION variable, according to criteria of safety and efficiency. Two novice controllers worked alternately with a highly-skilled controller under two conditions of heavy traffic flow. The independent variables, type of system, novice controllers, and rate of traffic entry were manipulated in a 2 x 2 x 2 factorial arrangement which provided for tests of significance between all three independent variables and their interactions. A return-to-base mission of 26 jet aircraft of both bomber and fighter types was simulated. These aircraft entered the traffic area approximately 60 naut. mi. from touchdown at partially randomized positions and times and at altitudes between 25,000 and 40,000 ft. In the more difficult problems, aircraft entered at the average rate of one per minute. In problems at the slower of the two rates, aircraft entered at an average rate of one every 90 sec. All measures of system efficiency except Estimated Excess Delay Build-Up showed no differences between Systems, Controllers, or Rates of Entry. The delay criterion indicated a statistically significant difference between the two novice controllers in terms of time over and above a theoretical minimum landing time. Approximately equal numbers of conflicts (less than 30-sec. GCA gate separation) were found with both systems. Although one is not justified in extrapolating on the basis of the data for the two levels studied, there is a definite suggestion that at rates still higher than the 60 per hour, the Sector system of control may prove to be significantly superior to the In-Line system. At the two rates used here there were no statistically significant differences between the systems. However, at the higher of the two rates the Sector system showed a slight superiority with all measures of system efficiency. Only one of these two procedures (In-Line Control) is used extensively in present-day military air traffic control centers; it appears that the Sector system should be given extensive operational tests as an alternative procedure."--Abstract
Man and technology : outlines in engineering psychology by B. F Lomov( Book )

1 edition published in 1963 in English and held by 6 WorldCat member libraries worldwide

This book is one of the first works in the USSR elucidating problems of a new branch of science, engineering psychology. It contains experimental data on the problem of the reliability of the operator controlling machines; the quantitative capacity of analyzers; the characteristics of psychic processes and the structure of work activity. The work discusses the principles of design of indicator devices and control organs deriving from the peculiarities of the psychic activity of man, i.e. coordinating peculiarities of design of machines with the characteristics of the man controlling them. The results of both domestic and foreign investigations in the field of engineering psychology are summarized. The book is intended for use by engineers, psychologists, physiologists, and also university and technical university students
A study of visual performance using ophthalmic filters by Merrill J Allen( Book )

1 edition published in 1961 in English and held by 6 WorldCat member libraries worldwide

"A study of the visual performance through five regularly available ophthalmic filter glasses, five identical filter glasses uniformly coated to 10 percent transmission, and five other identical filter glasses with a gradient density coating transmitting 10 percent in the center of the lens and about 0. 1 percent at the top of the lens was made using a 7- by 8- by 24-foot atmosphere chamber to simulate flight under adverse glare conditions. Controlled atmospheric conditions and chamber wall luminances of 7000 foot-lamberts and 400 foot-lamberts were provided. The far point test target was a threshold 1/2° white spot variable in brightness relative to the surround. The near target was a randomly presented number target set in a Link Trainer instrument panel. Panel luminances ranging from 0.1 to 0.43 percent of fog room wall luminances were provided and the subject's response time to adapt to the near target after adjusting the threshold spot at distance was the measure of visual performance through the specific filter being worn. Six subjects were used. Approximately 10, 000 judgments were recorded and analyzed for this study. The average time (under average experimental conditions using all subjects) required to identify a target on the instrument panel without sunglasses was 0.5994 sec.; with ordinary sunglasses, 0.6093 sec.; with uniform coating, 0.7603 sec.; and with gradient coating, 0.5057 sec. These include over 300 findings for the "no sunglasses" to 1800 findings for the gradient coating. Differences in performance could be accounted for on the basis of overall transmission effects without regard to filter color. All observers disliked the yellow filters. Threshold distant target recognition through gradient density filters was the poorest at low levels but the best at high levels by a narrow margin. Vision tended to be as good or better unaided than with most filters for a distant threshold target at about 490 foot-lamberts. However, at about 7000 foot-lamberts, the gradient density filter was again superior."--Abstract
A study of the effects of ionized air on behavior by W. Dean Chiles( Book )

1 edition published in 1960 in English and held by 6 WorldCat member libraries worldwide

"The effect on human behavior of an atmosphere containing excesses of unipolar ions was investigated. Fifteen subjects were tested on a complex mental task, an additional fifteen performed a vigilance task, and twenty subjects indicated their attitudes through marking an adjective check list while exposed to five levels of air ionization. The ion conditions for each study were varied from a high excess of positive ions through a medium excess of positive ions, low ion (neutral), medium negative, and low negative. None of the differences found among the ion conditions for these tests were statistically significant."--Abstract
